Staging
Clinical staging of senile cataract is based largely on the visual acuity of the patient, as follows
-Hypermature cataract Patient generally sees worse than count fingers (CF) or hand motion (HM) owing to a dense white, deeply dark opaque brunescent, or Morgagnian cataract
-Mature cataract Patient cannot read better than 20/200 on the visual acuity chart
-Immature cataract Patient can distinguish letters at lines better than 20/200
- Incipient cataract or dysfunctional lens syndrome Patient reports visual complaints but can still read at 20/20 despite lens opacity confirmed via slit lamp examination
